Patent DE-3821469-A1 (DE)
Title: Method for transmitting data between two stations via optical waveguides
Inventor: BRAHMS MARTIN DIPL ING
IPC: H04L25/49
Filed: 1988-06-25
Abstract: A method is indicated for inserting an additional channel into a main channel in the transmission of data between two stations via optical waveguides. For this purpose, bits of the additional optical channel with a lower bit rate compared with the main channel are inserted in any given position at defined intervals which are known in the transcoder of the receiving station into a main optical channel emanating from the transcoder of the transmitting station, in each case instead of a double bit, and are removed once more at the receiving end from the main optical channel. The bits of the additional channel which are inserted into the main channel are double bits which are identical to a forbidden bit combination which is produced when the electric AMI code is converted into the optical CMI code. At the receiving end, the double bits of the main channel which are replaced by the bits of the additional channel are retrieved in accordance with the rules of the electric code by means of a sequential logic.
Patent DE-3825475-A1 (DE)
Inventor: ETZKORN HORST DIPL PHYS DR ING
IPC: G01D5/26
Filed: 1988-07-27
Abstract: An optical position transmitter comprises a movable code element (36). A light beam (44) is directed onto the code element. The coding of the code element (36) generates in the reflected light beam (44) sub-light beams having different optical path differences. This may be effected by stepped surface portions on the surface of the code element (36). The optical path differences are greater than the coherency length of the light of the light source (62). The reflected light beam is directed through a beam splitter (42) onto an interferometer for detection of the optical path differences. Interferences between sub-light beams are permitted by well-defined quick changes in the interferometer with determined path differences. Position signals can be obtained from the thus obtained "interference peaks".

Title: Antilock hydraulic brake system
Inventor: VOLZ PETER DR
IPC: B60T8/44
Filed: 1988-10-22
Abstract: In a brake system with slip control (Fig. 1), with a diagonal division of the brake circuits (I and II), the wheel brakes (31 to 34) are connected by way of main brake lines (62, 63) and branch lines (47 to 50) to the master cylinder (2) of the brake pressure transmitter (1), inlet valves (24, 25 and 29, 30), which are open in the absence of any current, being inserted into the branch lines. In addition inlet lines (45, 46) with non-return valves (38, 39) inserted into them are coupled to the main brake lines (62, 63), by way of which valves pressure medium is delivered into the brake circuits (I, II) by two hydraulic pumps (21, 26) in the event of any locking tendency of the vehicle wheels, which causes the pistons (6, 7) of the master cylinder (2) to return against the foot pressure (F). The wheel brakes (31 to 34) are finally connected by way of outlet valves (22, 23 and 35, 36), closed in the absence of current, to a return line (37), to which the suction line (61) of the two pumps (21, 26) is also connected. For positioning the working pistons of the brake master cylinder, flowmeters (90, 91) are provided, by means of which the volume of pressure medium remaining in the brake master cylinder can be determined. The volume is clearly linked to the position of the working piston. The delivery capacity of the pumps (21, 26) is determined as a function of the position of the working pistons, especially the position of the pushrod piston (6). This is done either by switching the drive M on and off, ... Original abstract incomplete. <IMAGE>

Patent DE-4020485-A1 (DE)
Inventor: IRASCHKO JOHANN DIPL ING
IPC: F16D65/16
Filed: 1990-06-27
Abstract: The disc brake with a brake yoke (2) straddling a brake disc (1) has a tensioner on one side. The tensioner comprises a cam lever (4) which can be rotated about an axis parallel to the brake disc plane and co-operates with a cross-piece (6). The ends of the cross-piece (6) are screwed to adjusting spindles (7, 8) on which bears a brake pad (10). The two adjusting spindles (7 and 8) are coupled via a toothed belt (12). Into recesses in the two adjusting spindles (7 and 8) projects a rotary drive (14 or 14') which can be driven by the cam lever (4) and cause the adjusting spindles (7 and 8) to be screwed in the direction of approach to the brake disc (1) during the application or release movement. The synchronised operation of both adjusting spindles (7 and 8) is thus produced via the toothed belt (12). The rotary drive (14) contains a one-way rotary coupling and a torque-limiting coupling which prevents the adjusting spindles (7 and 8) from rotating during the application and release movements. The dual arrangement of the rotary drives (144 and 14') provide redundancy so that, if one rotary drive (14 or 14') should become ineffective, the clearance adjustment function is maintained and the disc brake cannot fail as the pads subsequently wear.

Title: Extraction mechanism for baked items in baking plate cavities - has vertical wall with angled passages for ejectors, vertical chutes for ejected items and conveyors for baked items and empty plates
IPC: A21B3/18
Filed: 1990-08-31
Abstract: A mechanism for demoulding baked items from pot-shaped cavities in baking plates has a vertical wall with open-ended passages opposite each cavity. A vertical chute is arranged opposite every vertical row of cavities. Push rods are moved through the open-ended passages and enter the opposing cavities at an angle to demould the baked items which then fall into the opposing chute. A first conveyor belt horizontally aligned below the vertical wall collects the falling baked items and a second conveyor removes the empty baking plates. Each push rod is formed by a flexible plastic tube which is cut off to form a ring-segment of slightly less than a semi-circle. The end of the ring-segment is spoon-shaped. USE/ADVANTAGE - The appts. is used to demould baked items with high levels of adhesive ingredients e.g. honey and guarantees a damage and deformation free product.
